Hello doctor! I went for an ultrasound on November 13, 2020 and the doctor told me I was 6 weeks pregnant, the gestational sac was small compared to my gestational age. The doctor prescribed me medication and scheduled another ultrasound in 2 weeks. So I would like to ask the doctor, is it okay if the gestational sac is small compared to my gestational age at 6 weeks of pregnancy? I had my period on September 17, 2020, my period is irregular. This is my second pregnancy. Thank you doctor, I am very worried!

You may not know what fertilization is, how long does it take to know if you are pregnant, but in fact, fertilization and conception can only occur when sperm combines with egg cells. This process is not simple, it even takes a long time for sperm to reach the egg.
